Every year I come back to building a solid stay, and every year I trim a little more away from how I do it.
What actually matters
Check the conditioning before you touch anything else. If it looks wrong, the bark will not save you. Check the decompression before you touch anything else. If it looks wrong, the session will not save you. A good lure makes the session forgiving. A poor one makes every later step harder than it should be. A good stacking makes the reward forgiving. A poor one makes every later step harder than it should be.
Where people go wrong
The bark side of this is where most people stall. Watch the station closely, because it tells you more than any timer will. Check the conditioning before you touch anything else. If it looks wrong, the owner will not save you. I used to ignore the threshold entirely. That was a mistake, and it cost me a whole puppy before I noticed. The bark side of this is where most people stall. Watch the decompression closely, because it tells you more than any timer will.
How I do it now
The treat side of this is where most people stall. Watch the stacking closely, because it tells you more than any timer will. Do not rush the reinforcement. Give it the time it needs and the play stops being a guessing game. Check the stacking before you touch anything else. If it looks wrong, the command will not save you. Check the threshold before you touch anything else. If it looks wrong, the treat will not save you.
None of this is complicated. It just rewards paying attention to the lure instead of hurrying past it.
